What Our Team Says About Chill Merchant

Trusted by tradespeople across South East Queensland for a reliable, professional and rewarding place to work.

“We had a fantastic experience working with Mark and the team at Chill Merchants.

They installed a large air con system in our workshop and office where several high temp machines run all day. These ducted units are big and heavy, and I wanted experienced tradesmen doing the job, and that's what we got.”
